in corner entry yes ...maybe depending on roll center front to rear offset but most don't need it ...but on exit every set up theory book,manual, notes for the last 17years ive used has always stated narrowing rear track width will provide more grip on exit and if you payed attention in this thread most where having a problem with wash out on exit due to the natural drag of this car ...so thats why most of us where running narrow rear set-up and the reason why the car was developed with different rear pivot options but im not going to dig into that aspect
check out the Hudy set-up books ....probably the most used worldwide

isn't it very contra productive to go a short arm to narrow the rear?
because as far as i know a narrowed rear will make the car more grippy but the short arm has the opposite effect.

We have several hex and eventually several arm options on this car, so would be interesting to know the theoretical changes behind each!?

But when you narrow the rear end you will get a car that doesn't want to rotate around it's front end as much, basicly making it more grippy.
So it counteracts each other.

Ok cool, so potentially keeping the s4 arm instead of the Yz-2 arm, but using the 5mm or 4.3mm hex on the rear may be a useful thing to test!

On very high grip tracks it makes the steering less twitchy and also handles better in the rough.
This is per some setup sheets I'm seeing the last one being Lee Martins'.
I haven't tried them myself I like a ton of steering and a responsive car on the local indoor clay track. Definitely might try it on Astro.

Has anyone ran their YZ4 with adding -2.5 more kick up? If so what is the verdict? Thinking that running -2.5 inserts may help take some twitch out of the steering especially since I made a mistake in buying the 8 degree aluminum caster blocks when I should have bought 12.5 (I heard the 8 degree aluminum casters are closer to the 10 degree kit composite casters, however I am not sure if that is true.
Thank you
